Abstract

PROBLEM TO BE SOLVED: To enable visual inspection for an injector by rotating and moving the injector at a visual inspection area while tilting at a predetermined angle during the injector transfer. SOLUTION: An attachment consisting of an injector holder 1 and a rotary roller 2 is set swingably to a mount member 6. Many mount members 6 are arranged via an interval at a transfer conveyor 3. An injector A is transferred with the use of the transfer conveyor 3 along a guide 4 in a state while erected. The rotary roller 2 fitted to the injector holder 1 is separated free from the guide 4 at an area of a rotary driving mechanism 8 tilted to face a visual inspection area B formed during the transfer of the injector. The rotary roller is further tilted rearward by a pressing member to be pressed in touch with the rotary driving mechanism 8 because of its own weight. In consequence, the injector holder 1 is moved while rotated, so that a foreign matter such as dust or the like, a flaw, stain, etc., of the injector can be inspected visually and in liquid.

2. Description of the Related Art In a conventional visual inspection of a syringe, a conventional conveyor is used to hold the syringe between rollers, or to transport the syringe by sandwiching it between screws and transporting the syringe upright. In such a state, the robot is passed in front of the inspector in a state, and is rotated and moved in a viewing area.

[0003]

However, in this conventional type, when the syringe passes in front of the inspector, the transport member of the transport conveyor enters the background field of view and is obstructed, making it difficult to visually observe, and in addition, the syringe is scratched. There was a problem easily. In addition, since the syringe is passed upright in front of the inspector in the viewing area and moved with rotation, blind spots occur due to the illumination of the syringe, causing the syringe to be submerged in liquid or in the appearance. Visual inspection tends to be difficult,
There were drawbacks such as a high degree of fatigue of the inspector. In addition, it is conceivable to inspect the work such as a syringe at an angle in the visual area.However, changing the angle of the work due to the configuration impedes the transfer mechanism and prevents the visual background from being freely changed. The choice was difficult and problematic.
The present invention is intended to eliminate these conventional drawbacks, and allows the syringe to be tilted and rotated at a predetermined angle in a viewing area while being transported while the syringe is being transported. The handling operation is simplified, the inspection accuracy is significantly improved, and visual work can be performed efficiently.
An object of the present invention is to provide a method and an apparatus for visually inspecting a syringe, which can extremely easily detect dust, scratches, and dirt attached or mixed in the syringe and can reduce the degree of visual fatigue, at a low cost.
